脾为诸阴之首，统摄一身之血。在气为中气，在脏为心子。目之上睥属脾，下睥属胃。
上睥
内生红粒，名鱼子石榴，生红块，名鸡冠蚬肉。皆属风热，邪滞太阴，气血凝结所致。睥生
痰核，在皮里膜外，如樱如梅，由于气滞燥结，防有成疣之患。睛明穴有疮，名眼痈，日久
成管，名漏睛，属太阳郁热不宣。睥翻粘睑，属阳明胃火。上睥生肉粒，名偷针，下睥生肉
粒，名眼瘅。肿痛属风郁化火，不肿痛而时发时止，属劳伤心脾，肝木克土，是虚症也。上
睥宽纵，拳毛倒睫，红肿，属脾肺气虚挟风，不红痛，属中气下陷。下睥紧急，拳毛倒入，
属肝风克胃。下睥内生菌，属阳明湿火。两睥生癣，湿烂为风，焦枯为火，干涩属燥，脓窠
属湿。然有风中兼燥，火中兼风，湿中兼热，诸症宜细辨之。
肾为作强之官，伎巧出焉。应北方癸水，涵木制火，荣养血脉。瞳神内起星，邪郁肾阴

五星撩乱，视物 ，水为火反克，虚实皆有也。瞳神细小，火搏水阴也。瞳神散大，气不
裹精也。瞳神发白，水源干涸所致。黑珠满红，名胭脂内障，属相火上浮，水不能制。若瞳

The Spleen is the head of all Yin meridians and governs the blood of the entire body. In terms of Qi mechanism, it belongs to Middle Qi (Zhong Qi); in the Five Zang organs relationship, it is the son of the Heart. The upper eyelid belongs to the Spleen, and the lower eyelid belongs to the Stomach.
Upper Eyelid
Red granules growing internally are named "Fish Roe Pomegranate" (Yuzi Shiliu); red masses growing internally are named "Chicken Comb Clam Meat" (Jiguan Xianrou). Both belong to Wind-Heat pathogenic factors, stagnating in the Taiyin meridian, causing condensation of Qi and Blood. Phlegm nodules growing within the eyelid, located between the skin and the fascia, resembling cherries or plums, result from Qi stagnation and dryness condensation; one must guard against the risk of becoming warts. Sores at the Jingming (BL1) acupoint are named "Eye Carbuncle" (Yanyong); if they persist for a long time and form fistulas, they are named "Leaking Eye" (Loujing), belonging to the failure of Sunyang meridian stagnant heat to disperse. Eyelid eversion with adhesion to the lid margin belongs to Yangming Stomach Fire. Flesh granules growing on the upper eyelid are named "Stealing Needle" (Touzhen); flesh granules growing on the lower eyelid are named "Eye Dan" (Yandan). Swelling and pain belong to Wind stagnation transforming into Fire; lack of swelling/pain with intermittent onset belongs to labor damaging the Heart and Spleen, with Liver Wood overacting on Earth, indicating a Deficiency syndrome. Upper eyelid laxity and widening, with inverted cilia and redness/swelling, belong to Spleen and Lung Qi deficiency with concomitant Wind; lack of redness/pain belongs to sinking of Middle Qi. Lower eyelid tightness and urgency, with inverted cilia turning inward, belong to Liver Wind overacting on the Stomach. Fungus-like growths internally in the lower eyelid belong to Yangming Damp-Fire. Tinea growing on both eyelids: wet erosion belongs to Wind, scorching/dryness belongs to Fire, dryness/astringency belongs to Dryness, and pustules belong to Dampness. However, there are cases where Wind combines with Dryness, Fire combines with Wind, and Dampness combines with Heat; various symptoms should be carefully differentiated.
The Kidney is the Official of Vigor, from which skill and dexterity emerge. It corresponds to the Gui Water of the North, nourishing Liver Wood to control Fire, and enriching the vessels and blood. Stars appearing internally within the pupil indicate pathogenic factors stagnating in Kidney Yin. Scattered vision like five chaotic stars, with blurred vision, indicates Water being counter-controlled by Fire, occurring in both Excess and Deficiency patterns. A small pupil indicates Fire combusting Kidney Water-Yin. A dilated pupil indicates Qi failing to envelop Essence. A white pupil results from the drying up of the Kidney Water source. Redness filling the black cornea is named "Rouge Internal Cataract" (Yanzhi Neizhang), belonging to Minister Fire floating upward, unable to be controlled by Water. If the pupil also turns red, it is named "Blood Pouring into the Pupil" (Xueguan Tongshen), which is incurable. A white, trembling pupil indicates an established internal cataract, also incurable. A golden-yellow pupil indicates excessive Fire and exhausted Water, also incurable. Seeing flying sparks indicates non-interaction between Heart and Kidney. Seeing eyes full of fireflies indicates disharmony between Liver and Kidney. Seeing chaotic white stars indicates Qi deficiency of Lung and Kidney. Seeing vast black flowers indicates failure of Kidney Yang to store. Seeing white as yellow, red as purple, straight as crooked, and stationary objects as moving, along with dizziness when opening the eyes, constitutes the syndrome of "Extreme Yin and Flying Yang" (Jiyin Yangfei). A pupil of normal size and color (neither white nor red), but with the extinction of the Three Lights (San Guang - referring to the luster of the pupil, cornea, and sclera), constitutes true "Green Blindness" (Qingmang), which is considered incurable. All the above items are syndromes of loss of essence and blood nourishment. Indeed, since Water is generated by Tianyi (One of Heaven), it is essential to nourish it; when Water is sufficient and Essence is abundant, eye diseases will naturally heal.
